In development roadmap.
School advancement
In these early versions, it’s groundhog day — once you get through summer, you’re repeating freshman year. You should be able to advance in year, take different classes, and even eventually graduate.
Did you make sure to save the change with the discord link? Still says invalid. I can feel platforms but can't see them. So aside from going through a door to get the chest that contains a weapon, I can't see a thing. I can see that it's looks like a ship due to the background. That was a swift response that I wasn't expecting. Good to see. If there is any details that you need, I'll happy to provide, after discord gets fixed.
